Abstract

We derive analytical expressions for various fundamental parameters of an electrically narrow rectangular grating. These include tangential electric field over the aperture, equivalent admittance, aperture voltage and the reflection coefficient for the dominant Floquet mode. The grooves are assumed to be partially (or completely) filled with a lossy material. The loading material is simulated by applying the standard impedance boundary condition.
